I think at least now Nvidia should act upon this request. I am not sure whether they have done it or not but as per my knowledge I guess they havenít yet removed the restriction of volt limit in GTX 680. I really do like this card especially I like its performance after overclocking goes more advance but however as said the volt restriction has never made me to know the best performance that could be shown by this card. Everyone know that currently the voltage limit of GTX 680 is 1.175 Volts which I personally feel is too low and also not a good voltage to test the card for overclocking. If such a good card can do so well with 1.175 volts then I am sure it might also do well with higher volts. Please Nvidia respond to this request or try to free out the voltage limit of this card. Only then GTX users like us will be able to make out the best out of it.
